Litter-Robot: Waste drawer liner installation guide

Emptying Litter-Robot is easy as taking out the trash with custom-fit waste drawer liners, made specifically for Litter-Robot.

Litter-Robot does not require special bags or liners for the waste drawer, but clear bags work best. Customers often use 10- to 13-gallon clear kitchen garbage bags or large clear plastic grocery bags. Please note that waste level readings may be inaccurate when using a dark bag, especially when the drawer is empty. As clumps start to collect in the drawer, the readings will become more accurate.

Empty the waste drawer when indicated by the app or the flashing blue light on the control panel. How often you empty the waste drawer depends on the number and size of your cats. For two average-sized cats, twice per week is typical. For a single cat, once per week is usually sufficient.

Open a new waste drawer liner or bag.
For Litter-Robot 4: Wrap the edges of the waste drawer liner over the rim of the waste drawer.
For Litter-Robot 3: Roll down the edges of the waste drawer liner a few times. Push the rolled edges of the liner into each of the four tabs in the waste drawer.
Push the remainder of the bag into the bottom of the waste drawer and then slide the waste drawer closed. Make sure the bag does not come up past the top of the sides of the waste drawer, which can result in a false flashing blue "drawer full" light on the control panel.
Press the Reset button to zero the weight sensors.

If you use the Whisker app for Litter-Robot 3, press Reset Gauge in the Controls section of the app when you empty the waste drawer to reset the waste drawer level in the app.
